This one is slightly different. The thieves were more careful with how they're using the cards, and credit unions are being hit hard. One CU manager mentioned in the story said that they've gone through half their budget for credit fraud for the year -- IN JANUARY.
I have lunch at Wendy's once or twice a week, and I always use my debit card. I haven't seen any activity on my account since the information about the breech surfaced a month and a half ago, still, I should either start carrying more cash for lunch or use my credit card more. The credit card is still vulnerable to data breeches such as this, but American law gives you stronger protection and reduced liability for a credit card versus a debit card. The problem with going to cash for such transactions is that my bank doesn't have a branch or ATM down here, so I'd be getting nibbled by out of network fees.
